Thanks to everyone for all the good suggestions. In response to the request for more information on my driving conditions, I have driven in the past only around 10,000 miles per year (in my Ford Explorer, which is now history!). My mileage average was around 13 city and 19 highway. Living in Los Angeles, the climate is mild. No AC or heater is necessary (usually). I drive approximately 6 miles to work each day. The terrain is down one hill in one direction and up the same hill coming home.

I increased the tire air today to 40 psi and will use synthetic oil as suggested at 5K miles. I was just wondering if perhaps the computer could be set wrong so that it does not use as much electricity as necessary during acceleration.

As to my driving habits, I have tried to utitlize the mileage gauge and adjust my presure on the gas to get it maxed out. I do not brake hard and accelerate rapidly. That is why I was surprised to be getting so low a mileage.
